Before the start of training camps in July, the NFL will visit all 32 teams for what a league spokesman termed a “facilitated dialogue” about adopting a healthier atmosphere in its locker rooms. At each stop, former players will be among those leading a one-hour discussion before players, coaches and executives.

The 32-team tour will stop in Santa Clara next week. And Martin will be in the audience less than eight months after he left the Dolphins because of locker-room bullying he endured, with Incognito being his primary antagonist.

His thoughts on the NFL’s program?

“That’s the first I’ve heard about that,” Martin said. “I think the NFL does a great job in taking care of its players. I think they’ll continue to do that.”

According to an independent investigation into the Dolphins’ bullying scandal, Martin, 24, was a constant target of verbal harassment and ridicule in Miami’s locker room. As a result, the 2012 second-round pick became depressed, twice contemplated suicide and considered leaving the NFL after his rookie season.

Martin did leave the Dolphins after seven regular-season games last year and his exit made the NFL’s locker-room culture a national conversation. On Tuesday, Martin said his two months with the 49ers, who acquired for a conditional 2015 seventh-round pick, have been positive.

“It’s been great,” he said. “I’ve got no complaints. It’s a competitive environment, but everyone takes care of each other. So it’s been fun.”

It’s also a somewhat familiar environment for the former All-American at Stanford. Jim Harbaugh, 49ers offensive coordinator Greg Roman and defensive coordinator Vic Fangio were at Stanford during Martin’s career. In addition, the 49ers signed two of his college teammates – linebackers Shayne Skov and Chase Thomas – in May.

Asked if his new 49ers’ teammates initially walked on eggshells with him given his recent past, Martin suggested there’s been no awkwardness.

“I’ve been around locker rooms for a long time,” he said. “So everything’s normal. It’s been real welcoming. So I’ve just been excited to be a part of the team.”

This week, Martin has also been excited to return to practice.

He was back on the field Monday after he was sidelined for nearly four weeks because of mononucleosis. He lost 12 pounds because of his illness, which didn’t allow him to have any physical activity. His extended role as a sideline spectator has taken a toll on his conditioning.

“You can’t get back in football shape unless you’re playing football,” Martin said. “So it’s a little bit of a process, but I felt a lot better today than I did yesterday.”

Martin served as the first-string right tackle in place of Anthony Davis, who is rehabbing from offseason shoulder surgery. Harbaugh said the 49ers view him as a reserve tackle, but might eventually have him also dabble at guard – a position he’s never played.

Harbaugh also he said he welcomed next week’s discussion about the NFL’s locker room environment, a program inspired by the difficult start to Martin’s career. Harbaugh, whose mantra is “the team, the team, the team” has a no-hazing policy with the 49ers.

“I think it will be a good discussion,” he said. “I look forward to it. Don’t think it will hurt and I’m sure it will help.”
